Tarasova V. Development of the theory and methods of thermoeconomic analysis, synthesis, optimization of innovative thermo-transformation systems.

In the dissertation work a new methodological approach to the solution of the scientific and applied problem of improving the methods of analysis, synthesis and optimization for the improvement of thermodynamic and techno-economic indicators of thermal transformation systems during design and operation is proposed. In the work for the first time a universal thermo-economic model of steamcompressor transformers was developed, which differs from the known models by the fact that the scheme of distribution of exergy flows in the elements of the installation according to the functional criterion "fuel" and "product" does not depend on its target value, but depends only from the environmental parameters, which allows to simplify the algorithm of the model and automate the calculation of the thermo-dynamic efficiency of the transformers. The method of processing data monitoring of heat and cooling systems on the basis of heat pump technology with the application of modern methods of applied thermodynamics is developed, which allows real-time thermodynamic testing of the system operation with a limited number of measured parameters, including the operation of steam-compressor heat pumps and water cooled machines in partial load mode. An express approach to the design of a horizontal ground heat exchanger is proposed, which allows determining the conditions for the efficient use of energy of near-surface soil, taking into account the mutual influence of the heat consumption of the object and the selection of heat from the soil mass during the entire period of operation of the heat pump, as well as determining the cost of the installation of heat. In this case, the complexity takes into account the possibility of variability of depth-not the laying of ground heat exchanger and the step of parallel sections of the pipe. The developed and improved existing methods, practical results, methods and recommendations were used at the Institute of Renewable Energy (Kyiv), Comfort +Service Ltd. (Kharkiv), PJSC Scientific and Production Enterprise " Kholod" (Kharkiv), The Scientific and Technical Center of the Engineering Academy of Ukraine (Kharkiv) and in public organizations "New Energy" and "Agency of Local Initiatives" (Kharkiv), which is confirmed by the relevant certificates and implementation acts.
